I defined a series of rectangular areas to extract from the UK planet.osm, and in order to avoid adding urban areas to the database, I had to exclude small rural areas near the big cities.

There's also a large void from Bridgnorth in Shropshire all the way to the North Sea near Lowestoft which cuts off a lot of rural areas. There is a large void in the North of England - which includes part of the Northumberland National Park.

Re: [Talk-GB] Proper Rights of Way coverage map
just wondering: are any of the highway=footpath tags still in OSM database? I always used to use those for "legal rights-of-way footpaths with a footpath sign" until it became OSM-standard that highway=footway should be used for all paths regardless of legal status. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

True, though perhaps these aren't so important to show as most people interested in using rights of ways are going to be using them in the countryside. >I assume your render is looking for the designation tag?

It's a bit more sophisticated than that; see the URL for what I consider a right of way. Note that I tried a version with highway=footway,foot=yes added in, and got the same sort of pattern.

Quite a lot of PROW within the urban sprawl. These being ways that have had to be adjusted and realigned when housing development extended, but at least were maintained as a route. I assume your render is looking for the designation tag? A lot of footways I've added don't have that on them yet so wouldn't show up. How about a combined map to show the extent of this difference, if indeed that is the basis of your present version.

[Talk-GB] Proper Rights of Way coverage map
Hello everyone, Following on from the unintentional rights-of-way coverage map generated by zooming out from the OSM/First Edition mashup that I mentioned the other day, I've now done a script to generate a real one. It's available at http://www.free-map.org.uk/freemap/stats/statsmap.php That page also details what I consider "rights of way". It shows quite well which areas of England and Wales have good ROW coverage and which need a lot more work (a project for 2010, perhaps?) Also see the blog post http://www.free-map.org.uk/wordpress/?p=19 Note that these maps are generated from Freemap's copy of the OSM database, so might be up to a week out of date. I normally update Freemap weekly so some animations should be possible in future! Also note that areas immediately around the big cities are excluded from the Freemap database, but then they wouldn't have many rights of way anyway!
